METAL SHANK FOR SHOES.

Application filed March 16, 1922. Serial No. 544,153.

To all whom it may c'onccm:

Be it known that I, HELMEP. G. JOSEPH- SON, a citizen. of the United States of America, and a resident of East Lynn, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Metal Shanks for Shoes, of which the following is a specification.

This invention-relates to shank supports for boots and shoes and is particularly designed to be used in connection with welt shoes, the object of the invention being to provide a shank support adapted to be positioned between the down-turned rib of an inner sole to which the welt is attached.

The invention consists in a metal support curved to fit the shank and having a wide forward end provided with a V-shaped strengthening depression extending downwardly and an upwardly extending arch at its rear end.

The invention further consists in providing said support with vertical sides extending from end to end and terminating in inwardly extending flanges.

The invention further consists of certain novel features of construction and arrangement of parts which will be understood readily by reference to the description of the drawings and to the claims to be hereinafter given.

For the purpose of illustrating the invention, one preferred form thereof is shown in the drawings, this form having been found to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which the invention consists can be variously arranged and organized, and that the invention is not limited to the precise arrangement and organization of the instrumentalities as herein shown and described, except as required by the scope of the appended claims.

Of the drawings:

Figure 1 represents a plan of a shank support embodying the principles of the present invention.

Figure 2 represents a side elevation of the same.

Figure 3 represents a transverse section on line 3, 3 on Fig. 2.

Figure 4 represents a transverse section on line 4, 4 on Fig. 2, and

Figure 5 represents a transverse section on line 5, 5 on Fig. 2.

Similar characters indicate like parts throughout the several figures of the drawings.

In the drawings 10 is a metal plate considerably wider. at the front end, as inclicated at 11, than at the rear end, as indicated at 12. Openings 13 are provided by which the shank support may be secured to the inner sole but other securing members may be provided without affecting the principles of the present invention.

The forward end of the shank support is provided with a downwardly extending V- shaped portion 14:, thereby stiffening the shank where the stiffening is most required.

The rear end of the plate 10 is provided with an upwardly extending arched portion 15 which stiffens the shank support adjacent to the heel, when the shank support is positioned in a boot or shoe.

This plate 10 is adapted to be positioned between the downwardly extending rib of an inner sole of a welt shoe at a point where the welt is attached to said downwardly extending rib.

The opposite edges of the plate 10 are curved to conform to the shape of the inner sole and have vertical sides 16 which abut the downwardly extending rib of said inner sole. The upper ends of the vertical sides 16 are provided with inwardly turned flanges which bear against the under face of the inner sole. By means of these vertical sides 16 and the inwardly turned flanges 17, the entire shank support is stiffened and its curvature is retained under all conditions when the shank has been secured into a boot or shoe.

It is believed that the operation and many advantages of the invention will be readily understood without further description.

Having thus described my invention, I claim:

1. A metal shank support adapted to be positioned between the insole and outsole of a shoe and having vertical side walls shaped to fit between the downwardly extending rib of the insole and provided with inturned flanges adapted to rest upon the under face of said insole.

2. A curved metal shank support adapted to be positioned between the insole and outsole of a shoe and having vertical side walls shaped to fit between the downwardly extending rib of-the insole and provided with inturned flanges adapted to rest upon the under face of said insole.

3. A curved metal shank support adapted to be positioned between the insole and outsole of a shoe and having vertical side Walls shaped to fit between the downwardly extending rib of the insole and provided with inturned flanges adapted to rest upon the under face of said insole," said side walls being of equal depth throughout.

4. A curved metal shank support adapted to be positioned between the insole and outsole of a shoe having a wide forward portion and a relatively narrow rear portion and provided with upwardly extending vertical sides extending from end to end and of equal depth throughout, said walls being shaped to lit between the downwardly extending rib of the insole and having inwardly extending portions forming flat bearing faces adapted to rest upon the under face of said insole.

5. A curved metal shank support adapted to be positioned between the insole and outw sole of a shoe having a wide forward portion and a relatively narrow rear portion and provided with upwardly extending vertical sides'extending from end to end and of equal depth throughout, said walls being shaped to fit between the downwardly extending rib of the insole and having inwardly extending flanges extending from end to end and forming fiat bearing faces adapted to rest upon the under face of the insole.
